Summary (Intent)

This test case addresses the export of the required IFC entities for the exchange of global positioning information.

• Refer to Test Case Imports to know the prerequisites for the present test.

• The Expected Results section lists the material that will be used to assess the fulfilment of capabilities.

• This is a test-driven process: refer to the Validation Criteria to understand what is required by the test

Itemised Roots

The Test instruction addresses the import and export of the following IFC Entities & Concept Templates:

IFC Entities

These entities represent a test-specific subset of the wider AbRV_E2a exchange and the overall AbRV MVD. The scope of the test shall not be used as a definitive scope of the exchange, or of the MVD

• Model setup:
  1. IfcMapConversion
  2. IfcProjectedCRS

Concept Templates

These concept templates represent a test-specific subset of the wider AbRV_Ex exchange and the overall AbRV MVD, that must be correctly exported to meet the validation criteria. The scope of the test shall not be used as a definitive scope of the exchange, or of the MVD

• Project Context
  • Project Global Positioning

Model Dataset

This test case utilises the dataset collected in the Dataset folder and summarised in the table below. For more details on each item see Dataset description.

GeographicData	figure (jpg)	Geographic data relevant for the test

Test Case Imports

All validation criteria (and usages) of predecessors' tests shall be verified for this test too (regression test principle). Prerequisites for the present test case are listed below.

TI Code	Test Instruction Title	Comments
IFC4x3_AbRV-E2a-PJ01	Project Setup	none

Expected Results

For certification of capabilities the only source will be:

• n. 1 IFC file containing the information as requested. The file shall be named using the following syntax: MVDCodeExchangeCodeTestCode_SoftwareVendor.ifc (Example: IFC4.3AbRV_E2a_GL01_AmazingSoft.ifc)

Validation criteria

For this test case to be considered passed all capabilities listed in this section, and the ones of pre-required tests shall be verified, with no exception.

Global Positioning

Acceptance criteria For the Global Positioning capability, the validation procedure must verify that:

• IfcMapConversion entity is used to transform the local engineering coordinate system, often called world coordinate system (WCS), into the coordinate reference system of the underlying map.
• IfcProjectedCRS entity is used for representing the coordinate reference system of the map to which the map translation of the local engineering coordinate system of the engineering project relates.
